To all "whom it may concern.

Be it known that I, Finn) HUMrinn'Es, a citizen of the United States, and resident of lvaukesha, in the county of lVaukesha and State of ll isconsin, have invented new and useful ln'i'provements in Metal VVindows, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to metal. windows, and especially to windows particularly adapted for use in factories or the like, or for windows of other buildings in which the sash and frame are constructed of commercial rolled metal welded or otherwise secured together.

One of the objects of this invention is to provide a. window construction wherein means is provided for pivot'ally' supporting the sash upon the frame whereupon the window may be swung to open position and will in its closed position providea tight rain-proof construction.

Other objects will appear hereinafter, as this description proceeds, especially when considered in connection with the acc0m-- panying drawings, wherein:

Figure 1 is an inside view of a complete window constructedin accordance with this invention;

Fig. 2 is a fragmentary vertical sectional view, taken on the plane indicated by the line 2-2 of Fig. 1;

Fig. 8 is a similar view, showing the sash in open position; and,

Fig. 4 is a. fragmentary sectional view taken on the plane indicated by the line 4% of Fig. 2.

Referring now more particularly to the drawings wherein like reference characters indicate like parts'it will be noted that the window frame consists of a pair of side members 10 and upper and lower members,

11 and H2, suitably connected to form a rectangular frame. The side members 10 of the frame are ffrmed with laterally or inwardly extending flanges 13, projecting preferably from the veiticahedges of the side members. The front flange 13 of each of the side members is notched or cut away as at 1%, while the portion 15 of the flange adjacent the notched or cut-awa portion is bent inwardly to permit the sasi to extend therethrough as clearly illustrated in the drawings. The rear or inside flange 13 of 1923. Serial no. 641,153.

each side member stops abruptly at a point adjacent the notchedportion of the outside or front flange to provide a ledge or shoulder 16, upon which the sash is adapted to rest. x

The window sash is of rectangular form and is preferably formed of a plurality of T-irons 1? and angle irons 18, which are secured together in the manner illustrated in Fig. l, thus forming a rigid sash construction'. The flange 19 of the angle irons 18 is shouldered as at 20 by bendingthe same inwardly as clearly illustrated in Figs. 2 and 3. This shoulder portion is adapted to rest upon the ledge or supporting edge 16' of the flange 13. 1

Thus a pivotal connection is provided between the frame and sash for supporting the sash upon the frame, whereupon the sash may be swung to open or closedposition, as desired, connection between the sash Lil and frame being effected without the pro 7 vision ofhinges, pivot bolts, or the like.

The angle irons 18, when connected tothe i T-ironslr" of the sash provide what are substantially outwardly extending flanges, while the construction of the frame provides inwardly or laterally extending flanges, and it is by this means that the desired pivotal connection between the sash and frame is provided. Thus it will be seen that a window frame construction embodying the principles of this invention may not only be rigidly and durably nection between the sash and frame may be made simple and economical from the point of operation and manufacture.

lVhile one vention has been illustrated herein, it is not intended that the invention be unnecessarily limited, but reservation is made to make such changes as may come within the purview of the accompanying claims.

Having thus described the invention what is claimed is: I

1. In a window construction, a frame con'iprising opposed parallel members, each provided with a flange extending only a por tion of its length, and with a flange extending substantially its entire length, said last mentioned flanges being cut away intermediate their ends; and a sash having opposed parallel members positioned adjacent said frame members, said sash members having inwardly and downwardly extending shoal:

constructed but the con dered webs engaging and pivoting on the ends of said lirst mentioned frame member flanges, and additional webs passing through the cut-away portions of said second mentioned flanges.

2. In a window construction, a frame comprising opposed parallel members, each provided with a flange extending only a portion of its length, and with a flange extending substantially its entire length, said last mentioned flanges being Cut away intermediate their ends and provided adjacent thereto with inclined tongues; and a sash having opposed parallel members positioned adjacent said frame members, said sash members having inwardly and downwardly extending shouldered webs engaging and pivoting on the ends of said first mentioned frame member flanges, and additional webs having inclined portions passing through the cutaway portions of said second mentioned flanges and coacting with said inclined tongues.

3. In a metal window construction, a frame including a pair of parallel side channel members, each having the upper portions of one flange cut away, thereby forming supporting shoulders, the other flanges of said members being notched approximately opposite to said shoulders; and a sash having side members provided with inwardly and downwardly extending webs overlapping the upper ends of said first named flanges, said overlapping portions being adapted to term shoulders to rest and pivot upon said first named shoulders, said sash having additional oiiset webs extending through the notches of said second mentioned flanges.

4-.111 a metal window construction, a frame including a pair of parallel side chain 01 members, each having the upper portions of one flange cut away, thereby forming supporting shoulders, the other flanges of said members being notched approximately opposite to said shoulders; and provided adjacent thereto with inwardly bent tongues and a sash having side members provided with inwardly and downwardly extending webs overlapping the upper ends of said first named flanges, said overlapping portions'being adapted to form shoulders to rest and pivot upon said first named shoulders, said sash having additional ofliset webs extending through the notches of said second mentioned flanges, the offset portions of said webs engaging said tongues, when the sash is closed.

In testimony whereof, I aflix my signature.
